Regarding information our freind has come back with the following:

The definition of information is to be found here:
http://plato.stanford.edu/entries....logical
Groovy. Now ask them to apply this definition to nucleotide sequences -- the ones I provided above will do, or if you'd rather supply your own sequences, that works, too.

Methods of measuring information can be found here:
http://en.wikipedia.org/wiki.......om_walk
[after a cursory look at that wikipage]So your Creationist buddies have a protocol by which they can measure information (don't see it, myself, but if they're citing that wikipage as providing such a protocol, they must see it, right?). Again, groovy. Your next step should be, ask them to use that information-measuring protocol to determine how much information is contained in various nucleotide sequences, particularly pairs of sequences whose information content you then compare.

Hi everyone,

here was the answer I got from our friend Ioseb hopefully my translation works out ok:

------transcript starts here -----------

Southstar said: Well how do you determine the amount of information? what process do you use?

Ioseb said: Well I use the unit of measure on the base of the nucliotide molecule (DNA or RNA), expressed in thousands of bases (kb)

If your boy Ioseb really does measure 'information' by counting the nucleotides, he's already lost -- because by the number-of-nucleotides method for measuring information, any mutation which inserts extra nucleotides into a genetic sequence increases the information of that DNA! You should point this out. The lurkers will appreciate it.

By measuring the modifications taken place in the genomic sequence of the Malaria or HIV plasmoid through the years it is possible to quantify, how much has changed in terms of complexity, what has been gained and what has determined no change.

This is bafflegab. It is most certainly not a clear answer to the question of "how do you measure information?"; at best, it's a vague assertion about a perhaps-hypothetical method which possibly could measure information. Give Ioseb a pair of nucleotide sequences, one of which is a minor modification of the other. Ask him which of the two sequences has more information in it -- and insist that he show his work. He won't be able to, so make his failure utterly crystal-clear in the minds of all readers.  No matter how impressive his sciencey-sounding verbiage is, his inability to actually determine how much information is in a nucleotide sequence will go a long way towards convincing people that Ioseb is full of shit.

As I explained: a sequence A; let's say produces a protein B following 3 molecular processes which are at the base of life. (in extremely simple terms replication, transcription and translation) all that needs to be done is to verify how much this sequence has changed after the mutation so as to measure at least the quantity of nucleotides that diffirentiate it.

The phrase "at least" suggests that there's more to his information-measuring method than just counting nucleotides. Ask what else is needed, besides just the number of nucleotides.
